[xine-devel] [PATCH 0 of 2] ffmpeg video: make preview buffers optional

[Petri H. <phi...@us...>]

Preview buffers are used to initialize ffmpeg video decoder to mpeg1/2 mode. Following patchset makes preview buffers optional.
After this change all video decoders work without preview buffers.
Note that some decoders use preview buffers as normal data, some ignore those.
